Communism and socialism

There was a recent article about a mega mansion in California that just sold for $75 million dollars.

What caught the attention of 2setsofrules was the buyer was from China.

Isn’t China a communist country?  Who the heck has $75 million dollars from a communist country to spend on a  house?

Obviously, communism works better for some people than other people. Can you say two sets of rules?
